ACETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed .Tully 27, 1912. Serial No. 711,836.

T0 @ZZ whom t may concern:

Be it known that I, Jaton F. Hisnn, a citizen of the United States, residing at Dundee, in the county of Monroe and citate of Michigan, have invented certain new and useful improvements in Acetylene- (las Generators; and l' do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to acetylene gas apparatus, and it more particularly relates to an acetylene gas generator especially adapted for private dwellings and premises.

The primary object of the invention is to provide a thoroughly practical, efficient, safe, economical, convenient and easily manipulated apparatus of this character, and another object of the invention is to provide means for preventing the escape of gas in a building during a time when it is unoccupied.

Other objects and advantages may be recited hereinafter and in the claims.

In the accompanying drawings which form a part of this application, Figure 1 is a side elevation view of the complete apparatus, and Fig. 2 is an enlarged detail view of the bell-supporting and carbid feedactuating mechanism.

Referring to the drawings in which similar reference characters designate correspending` parts throughout the several views, the generator tank 10 is supported upon a base or frame 11, of any proper construction, and provided with an elevated portion 12 on which is seated the gas tank or container 13. rlhe tanks 10 and 13 communicate with each other through the medium of a connecting pipe or gas conduit 14, which preferably extends above the upper ends of said tanks, as shown at 14e. A yo-ke 15 is connected with the base or frame, at 16, and with the tank 10, at 17. A vertical guide rod 18 is secured to the upper portion ot the yoke 15 and to the bottom of the tank 13. l/Vithin the tank 13 is the bell 19, mounted to slide vertically upon the guide rod 18, without undue friction between the bearings and the guide rod. A. lead pipe 2.7 communicates with the tank 13, being secured to the bottom of said tank and extending` approximately to the top thereof, and through this lead pipe the gas is conveyed to suitable gas jets or burners (not shown), where it is consumed. The lead pipe 27 is intercepted by a pressure equalizing and regulating` device 2S. rlf'he valve member 34: is also provided with a thumb piece 35, by means of which it may be adjusted, for regulating the volume of gas passing through the equalizing device.

The lower cylindrical portion 37 of the hopper 37 and the upper cylindrical portion 49 of the feed spout, are connected together' by bolts 50 having hooked upper ends engaging in apertures in flanges 37, the lower ends of said bolts passing through. flanges L18 and being provided with suitable nuts.

rThe feeding` mechanism is adapted to be automatically actuated by the rise and fall of the gas bell 1D, through the medium of an intermediary transmission mechanism carried by the yoke 1.5 and consists of a vertieally disposed saw-toothed bar or ratchet which is pivotally secured on the yoke 15 through the medium of tongues 7l and bracket-s 72, and being` adapted to swing upward and laterally on the pivots 7 8, a suitable stop 74 heilig provided for limiting the downward movement thereof. A chain 75 is secured to the upper portion of the member 7 0 and the medial portion of a lever '76, which pivoted to the yoke 15 at 7G and is provided with a stop 76a, which is adapted to` contact with the yoke 15, for limiting the upward movement of the lever 76. A flexible member 77 is secured to the lever' 7G and is passed over aV pulley 78 and carries a weight 79 which normally rests on a shelf 80; but when the weight is removed from the shelf and allowed to swing upon the flexible member 77, the lever' 76 is thereby swung upwardly about its pivot 76 and carries the chain 75 and the ratchet 70 therewith.

The guide bar S1 is secured to the yoke 15, at its respective upper and lower ends, by means of screws` 81', said guide bar being spaced apart in pa allel relation to the vertical portion of the yoke 15, so as to leave a space 82 between the guide bar and yoke, and through this space extends the free end of a transmission arm S3, the other end of said arm being secured to the top of the bell 1). Adjacent to the end of the arm S3 is secured a carrier or lifter member consisting of an L-shaped member S4: having a second L-shaped member S5 pivoted thereto at 86, in such relation that certain arms of the respective L-shaped members are inV alinement with each other while the other arms of the L-shaped members are in spaced relation, being parallel and horizontally disposed. rIhe actuating arm 46 extends from the feed mechanism under the horizontal arm of the L-shaped member 84 and over the horizontal arm of the member 85 and is adapted to be lowered and raised respectively by these horizontal arms. A guide rod or bar S7 is secured at its top and bottom, respectively, to the guide bar S1, and in parallel relation thereto, so that a space 88 is provided between the guide bars 81 and 87, and through this space extends the arm 46, which is guided by said guide bars as it rises and falls. To the lower end of the bar S1 is secured a bracket 89 which supports a standard 90, having a at surface in parallel relation to the guide bars 81 and 87, said flat surface being adapted to contact with the lower end portion of the member 85, when pressure is applied on the horizontal portion of the member 85, while raising the arm 46.

In operation the tanks 10 and 13 are partly filled with water, and as is well known, the gas is generated by the combination of calcium-carbid and water within the generator tank.

In operation, assuming that the hopper 37 has been filled with carbid, and that the tanks 10 and 13 have been properly supplied. with water; the weight 7 9 would iirst be allowed to swing` upon the member 77, so as to hold the lever 76 in its raised position, thereby moving the ratchet so as to clear the space 82 and thereby allow free movement of the arm 83 within the space 82. The bell 19 would then be raised, by hand, and then lowered, so that the arm 46 would be caused to actuate the carbid feeder (not shown), and charge the tank 10 through the passage 49 and into the generator chamber. As soon as the carbid enters the water, gas is generated and the bell 19 is raised and carries the arm S3 therewith, thereby raising the free end of the arm, through the medium of the L-shaped lifter member S5. As soon as this lifter member has been carried above the upper end of the standard 90, the vertical arm of the lifter member will be swung laterally over the standard 90, by the pressure of the arm 46 on the horizontal arm of the lifter member, and so the arm 46 will remain stationary while the lifter member continues in its upward course, until the generation of gas ceases.

lVhen it becomes necessary to replenish the hopper 37 with carbid, the weight 79 is irst placed upon the shelf 80, so that the lever 76 and ratchet 70 will be in the position shown in Fig. Q. The bell 19 is then raised, so as to create a suction which will tend to draw the gas from the top of the generator chamber. The cap 39 is then removed, and

the partial vacuum which has been caused by raising the bell 19 will cause the gas to pass from the hopper 37 into the generator tank, thus preventing the escape thereof into the room wherein the plant is located while the hopper is being filled with carbid.

The flexible members 77 may be carried over a suitable system of pulleys (not shown), to any portion or portions of a building, so that the ratchet 70 may be raised or lowered by a person remote from the generator, so that the pressure of the bell 19 may be relieved or restablished, by simply placing the weight 7 9 upon the shelf SO or removing it therefrom, The flexible member 77 may be guarded by any proper means (not shown), while the weight 79 may be placed above the reach of children or within any secret closure (not shown). By this means, the owner of the plant may put the same out of operative relation, by placing the weight 79 on the shelf, and so the bell 19 will be prevented from descending, so that no pressure will be exerted on the gas in the tank 13. By this means, danger from escaping of gas may also be avoided, by thus relieving the pressure on the gas whenever the building is left unoccupied for a time.

It will be seen that a gas plant or apparatus of this character is fully capable of attaining the foregoing objects, and in a thoroughly practical and eiiicient manner.

I do not limit my invention to the exact details of construction, combination and arrangement of parts as described and illustrated herewith, but my invention may only be limited by a reasonable interpretation of the claims.
